MTV announced in February that they picked up Teen Mom 3, and the brand-new moms from fourth season of 16 & Pregnant are finally being revealed! Read on to find out who they are.

MTV will officially unveil the final cast on Nov. 3 during a taping of the Teen Mom 3 reunion in New York City with Dr. Drew. According to Onset Productions, the company that’s hosting the reunion, the ladies will discuss “new and old loves, schooling, legal situations, and their children’s terrible twos.”

RadarOnline confirmed Mackenzie and Alexandria back in May, but the final two spots were up for grabs — until Katie posted photos of her daughter Molli‘s first birthday to her Facebook account with visible camera crews in the background.

Briana also gave a not-so-subtle hint on social media about her future reality career. “Don’t be mad when you start seeing more of me on ur television screen,” she wrote on Twitter.
